The slicer's gear transmits motion from the motor to the blade: as with the meat grinder, fibre and nylon materials are chosen to be weaker than steel and break first in case of overload or jamming, protecting the motor; bronze gears are more durable but lack this protective function.

How to choose the right part: count the teeth (code Z, e.g. Z25, Z30, Z31) and check the diameter and centre hole. Some models have a toothed sector (a partial gear, not a full ring) instead of a full gear. Shock absorbers (inserts that cushion the impact on engagement, e.g. with a 6mm shock absorber) are an extra protection found only on some models.

Compatibility by brand: available for Atoma, Bizerba, Berkel, FIA Boston and Arsa — even with the same number of teeth, gears from different brands are often not interchangeable because of different hole size and mounting seat.

For meat grinder or mixer gears see Gears for Meat Grinder or Gear for Mixer.

Frequently asked questions

Why choose fibre/nylon over bronze?
Fibre and nylon break first in case of overload, protecting the motor; bronze lasts longer but in case of a jam the overload transfers to the motor.

What is a toothed sector?
It's a partial gear (not a full ring) used on some models instead of a full gear: the two are not interchangeable.
